Answer:
Cost of 4 muffins = $3.45
Cost of 12 muffins = (3 sets of x 4 muffins = 12)
Cost of 3 sets of muffins = $3.45 x3 = $10.35
Step-by-step explanation:
The answer is -4 because -4^7=-16384
Answer:
The two linear equation
x + y = 19.... Equation 1
0.55x + 0.75y = 12.65... Equation 2
Nedra purchased
9 Apples and 11 Oranges
Step-by-step explanation:
Nedra purchased apples and oranges at the grocery store. which two linear equations can be used to find the number of apples and oranges?
Let the number of apples be represented by x
The number of oranges by represented by y.
Hence,
Apples are $0.55 each and oranges are $0.75 each. If she spent a total of $12.65 for 19 pieces of fruit,
Hence:
x + y = 19..... Equation 1
x = 19 - y
$0.55 × x + $0.75 × y = $12.65
0.55x + 0.75y = 12.65.....Equation 2
Hence: we substitute 19 - y for x in Equation 2
0.55(19 - y) + 0.75y = 12.65
10.45 - 0.55y + 0.75y = 12.65
-0.55y+ 0.75y = 12.65 - 10.45
0.20y = 2.2
y = 2.2/0.20
y = 11 oranges
x = 19 - y
x = 19 - 11
x = 8 Apples
Answer:
there are 20 different combinations if that was the question.
Step-by-step explanation:
Formula :
Combination(event 1) times Combinations (Event2)
D + q = 40
.10d +.25q= $7.75
d +q = 40
d =40-q
.10(40-q) +.25q= $7.75
4 - .10q + .25q =7.75
4 +.15q =7.75
4-4 +.15q =7.75-4
.15q= 3.75
.15q/.15 = 3.75/.15
q = 25
d =40-25
d = 15
Check
.10(15) +.25(25)= $7.75
1.5+6.25=7.75
7.75=7.75
